PENCIL.

Appueatin inea April 4, 1921, seriai To all 'whom t may eoncem.'

Be it known that L RAYMOND T. BELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pencils, of which the following is a specification.

, Thisinvention relates to improvements in. pencils of the type in which the lead or crayon is adapted to be fed from the holder as the lead is consumed, and one of the objects of the invention is to improve and simplify the construction thereof and to produce a pencil of this character from a very small number of pants and which will at the -same-time be compact in construction, convenient for use and eifective and etlicient in operation.

To thev attainmentl ofV these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially theconstruction, combination and arrangement of fthe several parts hereinafter more fully described and claimed and shown in the accompanying drawing'illustrating this invention and in which- Figure 1 is a side elevation.

Figure 21s a longitudinal sectional view.

Figure 3 is a view partly in elevation and partly in longitudinal section of one of the -crayon or lead adjusting members,-

Figure 4 is an end view of Figure 5.

Figure 5 is an enlarged detail top plan( view of one end of the pencil.

Figure 6 is a longitudinal sectional view of Figure 5. 2 Figure 7 is a sectional view taken on line 7 7, Figure 9.

Figure 8 is an elevation of a detail. Figure 9 is a view of one of the end members of the pencil. L

Figure 10 is a horizontal sectional view of the sheath orbodyv of the pencil.

Referring more particularly to-the draw- 'ing the numeral 15 designates the sheath or body of the pencil, which may be `of any desired size and configuration and constructed of any suitable material but is preferablydconstructed' of light material such as woo Y This sheath 15 is provided with a central bore 16 extending throughout the length is rovided with No. 458,445. Renewed .my 19, 1924.

ing therewith and extending throughout the length of the sheath.' One end of the sheath 15 is reduced as at 18 for any suitable distance from the end and encompassing this reduced portion 18, is a sleeve 19, c'onstructf ed ofany suitable material, such as metal or the like: This sleeve v19 is provided with a circumferentially reduced portion 20 interv mediate its ends, and the sleeve is adapted to fit upon-.the reduced end 18 of the'sheath 15, and to be heldthere in any suitable manner, preferably by a shrink fit thereupon, and the external diameter of the sleeve 19 is*'pre'aferably slightly less/than the externaldiameter ofthe sheath 15 beyond the reduced portion 18. 'l

Theother end of the sheath -15 is reduced as at 21, and is adapted to receive a tip 22, which is also constructed of any suitable material and istapered as shown, a portion-of F one end of .the ti being of a diameter to receive the reduced) en`d 21 of the sheath 15, and these parts are secured together in any desired or suitable manner. A

The tip 22 may be of any desired length and a portion of the tip adjacent the -extremity 23 is cut to form a spring tongue 24,

which is deflected inwardly into the bore of the tip 22, so as to engage and rest vupon Nr the lead or' crayon 25, when the latter .is in b position, for the purpose of holding the lead or crayon against accidental displacement.'

This spring portion 24 is adapted vto yield when pressure is exerted `upon the lead25 lengthwise thereof so as to feed the extrem- @o ity of the lead through the end of the tip 22.

Arranged` within the bore 16 is a plunger member 26. one end of which-is adapted to engage the end of the lead 25. They other end of the plunger member 26 is preferably hollow as at 27, and is provided with suitable screw threads 28, to receive `a screw. element 29, the latter being rigidly connected with a-cap member 30, adapted to extend over the sleeve 19 and also 4the ad` jacent extremity of the sheath 15. Thls cap member 30 is provided with a sleeve j portion 31, having a spring tongue 32 cut therefrom and the tongue is deflected in- 1.05*

wardly into the sleeve portion 31, as shown.. more clearly in Figure 7. This spring tongue 32 is provided as ameans for yieldingly locking the cap 31 upon the end of the sheathand cofoperateswith the sleeve 1m 29v so that when the sleeve portion 31 is placed in position the spring tongue 32 will enter the @circumferentially cut away portion 420 of the sleeve 19 for holding the parts together under normal conditions, but

.when an abnormal stress is exerted upon the cap 30 to remove the same, the spring portion 32 will yield and permit the cap member 30 to become disengaged from the end of the sheath 15.

The screw member 29 is rigidly secured to the cap member 3() in any suitable manner preferably .by the extremity33 of the member 29 passing through a portion of the cap 30, and being riveted or otherwise secured thereto.

The cap member 30 may also be provided with a recessed portion 34, adapted to receive an eraser 35.

Projectingl laterally from the plunger meinber 26, and at any 'suitable point intermediate its ends is a pin or lug 36, the extremities of which project for some distance on each .sideof the plunger member l 26, so that'when the plunger member 26 is inserted lin the bore 16 of the sheath 15, the ends of the projecting element 36 will enter the slots 17, which latter extend throughout the length of the sheath, so that when `the cap member 30 is rotatedto rotate the screw 29, the latter will be fedinto or'out of -the---tubular portion 27 of the plunger 26, to advance or retract the plun-- 32 to yield andpass ont yof the circumferential groove20, in the sleeve 19, at which time the screw member 29 and plunger 26 may be withdrawn through the cap end of the sheath. j lf desired, portions of the sheath 15 may be shaped to form ma azines 37, in which an extra supplyiof leads may be carried.

With this improved construction it will be manifest that there is provided a pencil which is constructedl .of a minimum number f parts, in the present form of the invenf tion there being only six parts from which the pencil is lconstructed.

Obviously many changes may be made in the details of construction and in the if combination and arrangement of the sev' eral parts, within the scope of the claims,

without departing from the spirit of this invention.

What is claimed as new is 1. A pencil embodying a'sheath, a groove extending lengthwise of the sheath and communicating with the bore of the sheath, said groove being considerably smaller than the said bore, a tip -connected with the sheath, a plunger movable in the said bore, a lateral projection carried by the plunger,

extending into and movable in the groove for maintaining the plunger against turning, a screw element threaded into the end of the plunger for longitudinally moving the plunger, a cap rotatable upon the other end of the sheath, and to which cap the said screw element is secured for rotation, a shoulder on the end of the sheath, anda spring tongue formed from a portion or said cap entirely within theconnes of the edges of the cap andv extending in a direction transverse to the axis of the cap and co-operating with the shoulder for rotatably and yieldingly holding the cap inposition and for free removal.

2. A pencil embodying a barrel, a plunger therein, means for maintaining the plunger against rotation, means for moving i the plunger lengthwise of the barrel, a col-` lar encompassing one end of the barrel, said collar having a circumferentially reduced portion to form `a shoulder, a cap'engagin over the collar, and to which cap the secon recited means is connected for operation thereby, and a spring tongue formed from a portion of the said cap and extending into the cap, said tongue being adapted to engage under the said shoulder for rotatably and yieldingly holding the cap in position and for free removal, the said tongue extending in a direction transverse to the axis of the cap.

3. A pencil embodying a sheath, a plunger movable'in the sheath, means for moving the plunger, a cap carried by one end of the sheath and to which cap the said means is-operatively connected', a tip at the other end of .the sheath, and means for rotatably securing-the said cap 'in position for free detachment, the last recited means embodying a spring like portion carried by the .cap andV the c'onnes of the edges of the cap, and an amnular groove connected with the sheath and into which groove the said spring like portion projects.
